Which Groupset?

Yes. I think. BCD is the same.

yes; you have anything?

No.
I'm indicating you should buy something else and then stick one of ^^ those rings on.

Yeah can do; 165mm stuff hardly comes up on ebay etc. If I have to buy new then its more expensive that way unless I can get a 50/34 and only keep 34t on there. Its needed for a 1x9 setup.

Stop being a hipster about your crank length and just use man-sized ones.

its not for me

SRAM press conference currently happening at Eurobike, press embargoed until midday, presumably CET, before publishing any details.

Hopefully it's the announcement of their wireless electronic group set.

£2k.

Shut up and take my money SRAM.

Looks impressive. Will have to see the trickle down.

Finally a sram groupset that does front shifting well ;)

Also FSA has launched their prototype:

Plus Rotor is there atm with there unique shifting for their electronic groupset too..

FSA and Rotor groups can >>>>>>>>>

Will be perfect for your next sportive

So much this.
'Only' £1,180 for upgrading though.

Will the SRAM etap system work with any crankset / chain rings or does it have to be those new Red ones? Battery life? And you physically remove the batteries to charge them, but won't they become loose eventually from unplugging and plugging back in? Haven't read the article yet but will.

lulz

yes

a lot

no

How very dare you.

Read article. Seems interesting. Red cassette compatible only? Also this:

"Airea is a private system – it’s proprietary to SRAM, so no tech information is outside of the company"

Yet? Once it's available commercially surely someone could figure it out and, if they're so inclined, stand at the side of the road during races with a scrambling device to sabotage the signals?

Possible. Of course. Just look at the hacking of various cars in the US recently.

OP: Shimano, btw.

That's if you're not busy riding into any more innocent car doors

SRAMmed right into that door, he did. #toosoon?
